Beneath a hairy problem: Phylogeny, morphology, and biogeography circumscribe the new Miconia supersection Discolores (Melastomataceae: Miconieae).

Miconia is among the largest plant genera in the Neotropics and a taxonomically complex lineage. Indeed, molecular phylogenetic data shows that none of its traditionally accepted sections are monophyletic, preventing taxonomic advances within the genus. Miconia is the largest plant genus in the Brazilian Atlantic Forest, including three main lineages, the Leandra s.
